How to match the nitrogen machine with the air compressor: You should first consider the system parameters of your nitrogen machine to match the air compressor, and the pressure, flow rate, temperature and so on. There are many aspects to consider. It is best to know the parameter requirements of the nitrogen machine to match the air compressor, but the selection of air compressor must be larger than the required flow of your nitrogen machine system. Nitrogen production mechanism The air pressure source required for nitrogen equipment must be a dry, oil-free and clean compressed air source with a pressure above 0.6Mpa and below 0.8Mpa. Because the molecular sieve of the nitrogen production mechanism nitrogen equipment has the best adsorption effect between this pressure. Therefore, it is best to choose oil-free air compressors when selecting air compressors. Sometimes considering the price of oil-free air compressors is a little high, it is also necessary to choose micro-oil air compressors as far as possible, but the purification part behind the need to add oil remover to ensure the relative cleanliness of compressed air. If it is used in the food industry food nitrogen machine or recommended to choose oil-free air compressor.

So a nitrogen production mechanism nitrogen equipment in the end to choose how much air compressor? Here we have a calculation method, the purity of 99.9% of the nitrogen mechanism nitrogen equipment requires the amount of compressed air is 6 times the nitrogen production of the nitrogen mechanism nitrogen equipment, such as a 3 cubic nitrogen mechanism nitrogen equipment compressed air volume is not less than 0.3m3/min per minute. If the purity of 99.99% of the nitrogen production mechanism nitrogen equipment requires the amount of compressed air is 8 times the nitrogen production mechanism nitrogen equipment, such as a 5 cubic nitrogen production mechanism nitrogen equipment of compressed air per minute is not less than 0.6m3/min. General system: Air compressor out of the air intake tank, air tank out of the cold and dry machine and then into the nitrogen machine, out of the working equipment, nitrogen machine supporting the air compressor is actually very simple, mainly depends on the purity of nitrogen you need, the higher the purity of the air required greater, so that the power of the air compressor is larger, on the contrary, the general purity of 99% nitrogen nitrogen machine on the market most choose 3: 1 is equipped with nitrogen flow rate of 50 cubic meters per hour, the air compressor needs to treat 150 cubic meters of air, the general air compressor manufacturers marked by the air treatment capacity is marked by minutes or hours, the conversion can be done, as for the pressure of compressed air, the general nitrogen machine 0.8MPa.

A matching screw air compressor is 20% larger than the nitrogen machine. When selecting air compressor, the first thing to look at is the amount of disposal, and then look at the skill needs, although the general skills are now common, but in all walks of life, the application of skills will have a small amount of error, which is ultimately to look at the power of the compressor; In special cases, it can also be equipped with piston air compressors.

The first point, PSA nitrogen production mechanism nitrogen equipment center - molecular sieve

The second point, the selection of the world's most advanced molecular sieve to ensure the use of molecular sieve, special molecular sieve filling skills and molecular sieve active supplement equipment. Improve the nitrogen recovery rate of the nitrogen maker, and reduce energy consumption by 15-25% compared with other similar nitrogen makers to ensure the service life of the molecular sieve and reduce the adsorption "load" of the molecular sieve to improve the adsorption ability of the molecular sieve.

Third, the nitrogen machine on the pipeline controls the valve, and then causes the repair interest of the nitrogen equipment to be added and the equipment's operating function to be reduced. For the saved PSA nitrogen machine, it is important to deal with the sensitivity of its component valves, service life and repair questions, and some domestic valves have a relatively high repair rate.
